OK, I finally finished this last week, and posted my picture to a new thread.
Changed my mind and made it bigger than I had started out with.
Thanks so much, Eddie, for a most wonderful and clear tutorial.
Never would have attempted this without your very concise instructions.

Thank you. I meant to post it here when I finished, as I had posted it in progress, and then I had a Cocker Spaniel moment, and something else got my attention, and I forgot to post it here.
If I can do this from Eddie's tute........anyone can, and it is not hard doing it on the machine.

If you look back at pic 21, you can see that there are 4 pointed flaps on each block that converge in the center of each block. The tips of these flaps are tacked down with a few stitches to keep them in place while top-stitching the roll of fabric down over the "glass" fabric.
